Yesterday, I was doing an interview with one of my mentees. The questions she asked brought up some interesting points about MSI, our history and Columbus. I thought I would share 3 of the questions with the SoS readers:

How Did The Firm End Up In The Columbus Cyber Security Community?

Brent Huston:

“You have to remember that when I founded MicroSolved, back in 1992, there wasn’t a strong commercial Internet yet. Most of the electronic commerce efforts and digital business was done via dial-up or dedicated networks. I came to Columbus in 1988 to go to school and eventually ended up at DeVry. I was working at Sterling Software and doing a lot of experimentation with technology. Somehow, I got completely interested in security, hacking, phreaking and online crime. I took that passion and began to explore building it into a business. There were a few of us starting consulting companies back then, and Columbus was certainly an interesting place to be in the early 90s. Eventually, Steve Romig, from The Ohio State University started putting groups together – meeting at different parks and restaurants. That was the first place I really identified as the beginning of a security community in the city.”

Let’s face it, Supply Chain Security and Vendor Risk Management is just plain hard. There are a lot of moving pieces – companies, contacts, agreements, SLAs, metrics, reporting, etc. Suppliers also change frequently, since they have their own mergers/acquisitions, get replaced due to price changes or quality issues, new suppliers are added to support new product lines and old vendors go away as their product lines become obsolete. Among all of that, is cyber-security. MSI has a better and faster way forward – an automated way to reduce the churn – a way to get a concise, easy to use and manageable view of the security of your vendors’ security posture. This month, we will show you what we have been doing in secret for some of the largest companies in the world…

Vendors with good security postures often look the same as vendors with dangerous security postures, on paper at least. You know the drill – review the contracts, maybe they send you an audit or scan report (often aged), maybe they do a questionnaire (if you’re lucky). You get all of this – after you chase them down and hound them for it. You hope they were honest. You hope the data is valid. You hope they are diligent. You hope they stay in the same security posture or improve over time, and not the opposite. You hope for a lot. You just don’t often KNOW, and what most companies do know about their vendors is often quite old in Internet terms, and can be far afield from where their security posture is at the moment. MSI can help here too. This month, we will make our passive assessment tool available to the public for the first time. Leveraging it, you will be able to rapidly, efficiently and definitively get a historic and current view of the security posture of your vendors, without their permission or knowledge, with as frequent updates as you desire. You’ll be able to get the definitive audit of their posture, from the eyes of an attacker, in a variety of formats – including direct data feeds back into your GRC tools. Yes, that’s right – you can easily differentiate between good and bad security AND put an end to data entry and keyboarding sessions. We will show you how…

Supply chain security via manual processes just won’t scale. That’s why we have created a set of automated tools and services to help organizations do ongoing assessments of their entire supply chain. You can even sort your supply chain vendors by criticality or impact, and assign more or less frequent testing to those groups. You can get written reports, suitable for auditors – or as we wrote above, data feeds back to your GRC tools directly. We can test tens of vendors or thousands of vendors – whatever you need to gain trust and assurance over your supply chain vendors. The point is, we built workflows, methodologies, services and tools that scale to the largest companies on the planet. This month, we will show you how to solve your supply chain security problems.

You can also touch base with me on Twitter if you have questions (@lbhuston). We hope to hear from you if you truly love deep diving on data and hammering out the truth from content all around the web!

PS – Don’t worry, we know we have to train you. We are looking for people with strong core skills, an eagerness to learn and out of the box thinking. We’ll teach you the rest… 🙂

I wanted to share with you a great FREE resource that I found on the Cisco web site that details a great deal of information about DNS and the best practices around securing it. While, obviously, the content is heavy on Cisco products and commands, the general information, overview and many of the ideas contained in the article are very useful for network and security admins getting used to the basics of DNS.

Additionally, there are great resources listed, including several free/open source tools that can be used to manage and monitor DNS servers.

If you are interested in learning more about DNS or need a quick refresher, check this article out.

Several other resources are available around the web, but this seems to be one of the best summaries I have seen. As always, thanks for reading and let me know on Twitter (@lbhuston) if you have other favorite resources that you would like to share.

Here is the description from their site:Lynis is an auditing tool for Unix/Linux. It performs a security scan and determines the hardening state of the machine. Any detected security issues will be provided in the form of a suggestion or warning. Beside security related information it will also scan for general system information, installed packages and possible configuration errors.

This software aims in assisting automated auditing, hardening, software patch management, vulnerability and malware scanning of Unix/Linux based systems. It can be run without prior installation, so inclusion on read only storage is possible (USB stick, cd/dvd).

As you can see, it has a wide range of capabilities. It is a pretty handy tool and the reporting is pretty basic, but very useful.

Our testing went well, and overall, we were pleased at the level of detail the tool provides. We wouldn’t use it as our only Linux auditing tool, but is a very handy tool for the toolbox. The runs were of adequate speed and when we tweaked out the configs with common errors, the tool was quick to flag them.

Overall, we would give it a “not too shabby”. 🙂 The advice is still a bit technical for basic users, but then, do you want basic users administering a production box anyway? For true admins, the tool is perfectly adequate at telling them what to do and how to go about doing it, when it comes to hardening their systems.

Give Lynis a try and let me know what you think. You can give me feedback, kudos or insults on Twitter (@lbhuston). As always, thanks for reading!

At MSI, we know security doesn’t exist for its own sake. The world cares about business and so do we. While our professional and managed service offerings easily empower lines of business to work with data more safely, we also offer some very specific business process focused security services.

Attackers and criminals go where the money is. They aren’t just aiming to steal your data for no reason, they want it because it has value. As such, we have tailored a specific set of security services around the areas where valuable data tends to congregate and the parts of the business we see the bad guys focus on most.

Lastly, we have also found several areas where the experienced eyes of security experts can lend extra value to the business. Sometimes you can truly benefit from a “hacker’s eye view” of things and where it’s a fit, we have extended our insights to empower your business.

Here are some of the business focused offerings MSI has developed:

Mergers & Acquisitions (M&A) practice including:

Pre-negotiation intelligence

Pre-integration assessments

Post purchase threat intelligence

Accounting systems fraud testing

ACH & wire transfer security validation

End-to-end EDI (Electronic Data Interchange) security testing

Business partner assessments

Supply chain assessments

Executive cyber-protection (including at home & while traveling abroad)

MSI knows that your business needs security around the most critical data and the places where bad guys can harm you the worst. We’ve built a wide variety of customized security solutions and offerings to help organizations harden, monitor and protect the most targeted areas of their organization. At MSI, we know that information security means business and with our focused security offerings, we are leading the security community into a new age.

For many decades now the human race has benefitted from the evidentiary value of surveillance videos and audio recordings. Human beings cannot be relied on to give accurate accounts of events that they have witnessed. It is a frustrating fact that eye witness testimony is highly inaccurate. More often than not, people are mistaken in their recollections or they simply fail to tell the truth. But, with some reservations, we have learned to trust our surveillance recordings. Sure, analog videos and audio recordings can be tampered with. But almost universally, analysis of such tampered material exposes the fraud. Not so anymore!

Virtually every camera, video recorder and audio recorder on the planet is now digital. And it is theoretically possible to manipulate or totally forge digital recordings perfectly. Every year now, computer generated images and sounds used in movies are becoming more seamless and convincing. I see no reason at all why we couldn’t make totally realistic-appearing movies that contain not a single human actor or location shot. Just think of it: Jimmy Stewart and John Wayne, in their primes, with their own voices, starring in a brand new western of epic proportions! Awesome! And if Hollywood can do it, you can bet that a lot of other less reputable individuals can do it as well.

So what are we going to do about surveillance recordings (everything from ATMs and convenience store videos to recordings made by the FBI)? We won’t be able to trust that they are real or accurate anymore. Are we going to return to the old days of relying on eye witness testimony and the perceptiveness of juries? Are we going to let even more lying, larcenous and violent offenders off scot free than we are today? I don’t think we as a society will be able to tolerate that. After all, many crimes don’t produce any significant forensic evidence such as finger prints and DNA. Often, video and audio recordings are our only means of identifying the bad guys and what they do.

This means that we are going to have to find ways and means to certify that the digital recordings we make remain unaltered. (Do you see a new service industry in the offing)? The only thing I can think of to solve the problem is a service similar in many ways to the certificate authorities and token providers we use today. Trusted third parties that employ cryptographic techniques and other means to ensure that their equipment and recordings remain pristine.

But that still leaves the problem of the recordings of events that individuals make with their smart phones and camcorders. Can we in all good faith trust that these recordings are any more real than the surveillance recordings we are making today? These, too, are digital recordings and can theoretically be perfectly manipulated. But I can’t see the average Joe going through the hassle and spending the money necessary to certify their private recordings. I can’t see a way out of this part of the problem. Perhaps you can come up with some ideas that would work?

Is your organization’s information security program stuck in the era of perimeter firewalls and anti-virus software? Are you a Chief Information Security Officer or IT Manager stuck with the unenviable task of bringing your information security program into the 21st Century? Why not start the ball rolling with a business impact analysis (BIA)? It will provide you with a wealth of useful information, and it takes some of the weight from your shoulders by involving every business department in the organization.

BIA is traditionally seen as part of the business continuity process. It helps organizations recognize and prioritize which information, hardware and personnel assets are crucial to the business so that proper planning for contingency situations can be undertaken. This is very useful in and of itself, and is indeed crucial for proper business continuity and disaster recovery planning. But what other information security tasks can it help you with?

When MSI does a BIA, the first thing we do in issue a questionnaire to every business department and management function in the organization. These questionnaires are completed by the “power users” of the organization who are typically the most experienced and knowledgeable personnel in the business. This means that not only do you get the most reliable information possible, but that one person or one small group is not burdened with doing all of the information gathering. Typical responses include (but are not limited to):

A list of every business function each department undertakes

All of the hardware assets needed to perform each business function

All of the software assets needed to perform each business function

Inputs needed to perform each business function and where they come from

Outputs of each business function and where they are sent

Personnel needed to perform each business function

Knowledge and skills needed to perform each business function

So how does this knowledge help jumpstart your information security program as a whole? First, in order to properly protect information assets, you must know what you have and how it moves. In the Top 20 Critical Controls for Effective Cyber Defense, the first control is an inventory of devices and the second control is an inventory of software. The BIA lists all of the hardware and software assets needed to perform each business function. So in effect you have your starting inventories. This not only tells you what you need, but is useful in exposing assets wasting time and effort on your network that are not necessary; if it’s not on the critical lists, you probably don’t need it.

In MSI’s own 80/20 Rule of Information Security, the first requirement is not only producing inventories of software and hardware assets, but mapping of data flows and trust relationships. The inputs and outputs listed by each business department include these data flows and trust relationships. All you have to do is compile them and put them into a graphical map. And I can tell you from experience; this is a great savings in time and effort. If you have ever tried to map data flows and trust relationships as a stand-alone task, you know what I mean!

Another security control a BIA can help you implement is network segmentation and enclaving. The MSI 80/20 Rule has network enclaving as their #6 control and the Top 20 controls include secure network engineering as their #19 control. The information from a good BIA makes it easy to see how assets are naturally grouped, and therefore the best places to segment the network.

How about egress filtering? Egress filtering is widely recognized as one of the most effect security controls in preventing large scale data loss, and the most effective type of egress filtering employs white listing. White listing is typically much harder to tune and implement than black listing, but is very much more effective. With the information a BIA provides you, it is much easier to construct a useful white list; you have what each department needs to perform each business function at your fingertips.

Then there is skill and security training. The BIA tells you what information users need to know to perform their jobs, so that helps you make sure that personnel are trained correctly and in enough depth to deal with contingency situations. Also, knowing where all your critical assets lie and how they move helps you make sure you provide the right people with the right kind of security training.

And there are other crucial information security mechanisms that a BIA can help you with. What about access control? Wouldn’t knowing the relative importance of assets and their nexus points help you structure AD more effectively? And there is physical security. Knowing where the most crucial information lies and what departments process it would help you set up internal secure areas, wouldn’t it? What other information useful to setting up an effective information security program can you think of that is included in a proper BIA?

Thanks to the attendees and speakers who participated yesterday in the 3rd Annual ICS/SCADA Security Symposium. It was another great event and once again, the center of the value was in the interactions of the audience with the speakers and each other. It’s great to hear asset owners discuss what is working, what is challenging and what is critical in their minds.

Thanks again to those who attended and contributed to making this event such a wonderful thing again this year. We appreciate it and we can’t wait until next year to do it all again.
